ZoomX foam and full-length plate optimize energy return. The Dragonfly is for the cross-country barrier-breakers, the flurry-finishers who refuse to give in to the elements. It’s our fastest distance spike on the track built to go off-road. ZoomX foam adds a jolt of energy return while a wider base helps give you peace of mind in inclement conditions. Speed up the Tempo The combination of full-length ZoomX foam and a full-length plate optimizes resiliency and energy return while staying lightweight. Stay Dry The partial Vapor Weave upper helps keep the shoe light even when wet. The soft, engineered mesh toe box helps keep your toes and forefoot comfortably contained. Stay Secure An added arch band helps give you a secure fit in muddy conditions and a supportive feel on uneven terrain. Wider Base Extra width on the base of the shoe provides extra stability and confidence on all surfaces.
